# Plank workout vs 30 day

The clearest difference is rating: 30 day at 4.7 against Plank workout's 4.0. 30 day also leads on update cadence (every 9 days vs every 4 months) and ratings volume (155 vs 2). Plank workout's advantage is ads (none vs shown) and review sentiment (88% vs 75%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Plank workout sells 1 one-off in-app purchase and 30 day sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

30 day holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: 30 day has 155 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 88% of Plank workout's written reviews are positive against 75% of 30 day's, so the app with the better star average is not the one people write more warmly about.

Plank workout ships an update every 4 months, 30 day every 9 days. The most recent releases landed on October 12, 2026 and October 27, 2026 respectively.
